This is the all knowing entity that lives inside Zeroll's brain. It knows about almost all the types of monsters and gives information about them to Zeroll as and when required.
It's prime function is to ensure Zeroll's safety and to provide some recommended actions to Zeroll in order to help him during battles.
This system however can not force Zeroll to obey it, and only acts as an advisor to him. He also stores all of Zeroll's weapons, armours, gold and other items and only allows Zeroll to retrieve these as and when required.
This is the last chapter of the BACKGROUND series for now. If you feel I've missed some characters or think that there is some other important characters I should add backgrounds of, then please let me know in the comments.
